Description

一种全球移动通讯系统四频收发的装置及设备 技术领域
本发明涉及全球移动通讯系统（GSM )信号收发领域， 特别是指一种 GSM四频的收发装置及设备。 背景技术
由于 GSM 手机的普及以及低成本的优势， 其市场占有率较高。 GSM 手机的成本主要集中在射频收发芯片、 功率放大器（PA )、 天线开关。 目前 较为常见的低端手机基本都是 GSM双频手机， 这是由于目前进行 GSM四 频手机的设计会带来更高的成本。所述 GSM四频手机是指支持四种频段包 括 850Mhz频段、 900Mhz频段、 1800Mhz频段及 1900Mhz频段的手机。
如图 1所示， 为 GSM四频手机发射与接收的硬件架构图， 包括天线开 关 101、 滤波器 102、 PA 104、 射频收发芯片 103 , 其中， 天线开关 101将 从天线接收的信号发送给滤波器 102滤波后，发送给射频收发芯片 103; 射 频收发芯片 103将要发送的信号发送给 PA 104进行功率放大后， 发送给天 线开关 101 , 然后通过天线发送。 其中， 天线开关 101通过四条信号线与滤 波器 102相连， 所述滤波器 102包括 GSM850滤波器、 GSM900滤波器、 GSM1800滤波器、 GSM1900滤波器， 滤波器 102对不同频段的信号进行滤 波是通过其内部的谐振器实现， 与所述谐振器的谐振频率同一频段的信号 为通带信号， 会被滤波器通过， 谐振频率以外的信号为阻带信号， 会被滤 波器滤除， 同时， 滤波器 102 的输出信号为了有效的抑制信号的误差， 输 出差分信号； 所述射频收发芯片 103 包括四个接收机与四个发射机， 其中 四个接收机分别用于接收四个滤波器发送的差分信号， 并对接收的差分信 号进行功率放大， 四个发射机分别用于将各自接收号转换为射频信号后， 发送给 PA 104; PA 104通过传输四个频段的四条信号线同天线开关 101相 连； 四频天线开关成本较高， 且天线开关通过八条线路同滤波器 102及 PA 104相连， 需要通过三条逻辑控制线控制开关的状态； 同时， 滤波器 102通 过四组差分信号线与射频收发芯片 103相连， PA 104也需要通过四条线路 与射频收发芯片 103相连， 在提高成本的同时， 线路也比较复杂， 线路较 多造成布线困难。
目前， 随着接收机、 PA放大能力的提高， 通常釆用图 2所示的 GSM 四频收发硬件架构， 与图 1不同之处在于， GSM850滤波器与 GSM900滤 波器共用一组差分信号线与射频收发芯片的接收机相连， GSM1800 与 GSM1900共用一组差分信号线与射频收发芯片的接收机相连， GSM850频 段与 GSM900频段共用一个发射机发送信号， GSM1800频段与 GSM1900 频段共用一个发射机发送信号， PA通过两条信号线路与天线开关相连， 其 中一条线路用于传送 GSM850、 GSM900 频段的信号， 一条线路用于传送 GSM1800、 GSM 1900频段的信号， 这样简化了发射线路与接收线路， 减少 了两个发射机与接收机， 但天线开关通过六条信号线同滤波器及 PA相连， 仍需要通过三条逻辑控制线控制， 四频天线开关的成本仍然没有降低。 发明内容
